Phys.org / Bacterial defense system builds DNA in unexpected new way to stop viruses
Scientists at Stanford University have discovered that DRT3, a unique defense system found in bacteria, creates DNA to protect against viral infections. DRT3 is made up of two different enzymes called reverse transcriptases, ...
Medical Xpress / Age, sex, and cancer type can influence risk of subsequent cancers among survivors
The risk of developing a subsequent primary cancer varied significantly by age at initial diagnosis, sex, and type of first cancer, according to a study by Oxana Palesh and Susan Hong and colleagues at Virginia Commonwealth ...
Tech Xplore / Robotically assembled building blocks could make construction more efficient and sustainable
Robotically assembled building blocks could be a more environmentally friendly method for erecting large-scale structures than some existing construction techniques, according to a new study by MIT researchers published in ...
Phys.org / Stick-on gel delivers drugs directly to plants to clear infections quickly
A stick-on gel for plants could one day offer a simple, safe and targeted way to treat diseases and pests. Engineers at the University of California San Diego have developed an adhesive gel that can be loaded with substances, ...
Phys.org / Universal patterns emerge across 22 languages, mapping how vocabularies evolve
Human languages are known to have grown and changed considerably over the course of history, often reflecting technological, cultural, and societal shifts. Studying the evolution of languages can thus offer valuable insight ...
Phys.org / Bowhead whale recovery reflects century-old whaling patterns
An international study led by Adelaide University has found bowhead whale populations are recovering only in stocks where large areas of hazardous sea ice conditions limited devastating hunting centuries ago. The research ...
Phys.org / Soil, not fertilizer, is primary source of nitrogen gas loss in rice paddies, study reveals
Rice production is heavily dependent on nitrogen fertilizers, particularly in China, where application rates are two to three times the global average. At the same time, a large amount of nitrogen is lost to the environment—mainly ...
Science X / Electrochemistry captures coffee's taste, powering a more consistent cup
It takes a surprising amount of work to keep coffee consistent cup to cup. An electrifying new approach from University of Oregon researchers could make the task easier. They've discovered a way to measure the flavor profile ...
Medical Xpress / Adversity across life linked to greater frailty and faster biological aging
Published in BMC Medicine, the study analyzed data from over 150,000 participants and found the strongest associations in people who experienced adversity in both childhood and adulthood. These individuals were more frail ...
Phys.org / Deep under Antarctic ice, a long-predicted cosmic whisper finally breaks through in 13 strange bursts
A detector buried deep in Antarctic ice has captured the first experimental evidence of a predicted but never-before-seen phenomenon: radio pulses generated when high-energy cosmic rays slam into the ice sheet and trigger ...
Medical Xpress / Scientists create first-ever 'smell map' of the nose's smell receptors
For most of us, the sense of smell is an integral part of everyday life; it plays a critical role in providing information about our surroundings, alerting us to potential dangers, enhancing our sense of taste, and evoking ...
Tech Xplore / Bananas, cups and peelers: Robots learn how to handle curved objects like fruits and tools
It does not take much to confuse some robots. A machine might be great at handling a simple object like a box, yet when it tries to work with a more irregular shape like a banana, it often fails.
